What is considered a "pageview"

Question

My main index.html page consists of two parts (it is written in html and jquery / javascript):

• fixed heading that is always at the top of the page
• the content page loaded when the user clicks the button (i.e., click the “blog” button, and the div tag “content” loads with the content of the blog. Click “about” and the div tag “content” loads w / page about us.

When the user clicks a button on the page, index.html and the header are NOT reloaded; only the div tag "content" in index.html is updated with new information.

I use CPM ads. This may sound like an obvious question, but since the user stays at “index.html” and doesn’t explicitly go to the “blog.html” page or the “about.html" page, will it hurt my ads? Or ad networks (buysellads.com, etc.) smart enough to realize that a user is loading new content implicitly?

EDIT: the ad will be in / in the fixed part of the header, not in the part of the content

Answer 1

In general, advertisements for CPM, CPI, CPV, etc. based on the loading of ads, excluding reload operations from the ad itself.

With that said, since you are not actually changing the page, but rather updating the contents of the div container, you are not creating a new heading impression, so do not increase the number of CP *.
